Tutorial 7 - Primitive extension for the back of the head

If you go to Photoshop to the reference guide, you need to look at how the topology flows to use the topology as a reference. Define key lines in the neck area; it doesn’t need to be precise. We want to bring lines going out through the shoulder. You want to isolate the ear. We have a line under the jaw, under the ear and behind the ear. Also lines to show the folds of fat in the back of the neck.
Assign this map to the reference plates. If you had trouble finding the reference plates go over to display>hide frozen objects> uncheck.

Make a sphere and use the geometry to make the back of the head. Create a sphere. Turn on edges (F4 on the keyboard) so we can see how they are all lined up and we want to do this in main views. Roughly position it over our head, ALT X will make it semi transparent. You want to orientate the poles of the sphere, as there are so many triangles. Rotate the sphere so the poles are where the ears would be. Scale to fit. Take a closer look at the geometry and how it fits with the existing geometry. You can increase segment size to fit that of the face you have modelled. Edit poly > polygon > turn on the paint selection marquee. Start painting. You do not want interior polys and we only really want the back of the head. Once selected, then delete. Select all the faces on the right hand side. If we don’t do this we will get all sort of duplicate polygons that we don’t need.
Need to line these up, vertex mode> turn on snap, we want to configure our snap option as vertex, and now we go to move tool and click and drag to various points. Line up the closest ones first. Turn on soft selection, so that there are no shape edges.
Turn on soft selection. If you need more control you could use the falloff values or adjust the curve.
Turn off soft selection and continue to align. Press Alt X to get the surface back.
Select edge with shift to create new polygons for the neck area.
Because there are a lot of points, it makes things difficult. Use a smoothing algorithm for this. Simplify the geometry. Hide the reference plates. Select every other edge > Ring, it selects the edges that are parallel to those you have selected. Click on ring > edit geometry > collapse. This makes the geometry easy to modify and work with. I have highlighted the jugular vein and collar bone. We now go ahead and attach the head to the face so that we can see it on both sides. Select face >edit poly > edit geometry > attach, click on attach and on object that we wish to make the current one. The head is now attached. You can test to make sure that all the vertices are one. Go to paint option, go ahead and select several of the vertices, press on settings box on weld.
